HAYSTACKER.

Specification of Letters Patent.

Patented July 11, 1922.

Application filed January 27, 1921. Serial No. 440,438.

To all whom it may concern:

Be it known that I, JOSEPH F. CHLADEK, a citizen of the United States, residing at Niobrara, in the county of Knox and State of Nebraska, have invented certain new and useful Improvements in Haystackers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in hay stackers, although, it is not to be restricted to this particular use since it may be effectively used for various other pur poses, such as for loading wagons with hay and straw, hoisting artic es, etc.

One object of the invention is to provide a device of this class wherein the load carrier is acted on by a combination of levers .which serve to equalize the pull and render it uniform throughout. the entire upward movement of said carrier.

Another object of the invention is to pro vide a device of this class embodying a structure which reduces the amount of pull to a minimum and in turn reduces the distance of travel of the power, which in most instances will be horse-power. Thus, a single horse will be suflieient to accomplish the desired result and as the distance which it must travel is comparatively short, much time will be saved.

A further object of the invention is to generally improve upon devices of this class by the provision of one of extreme simplicity and durability, which will efiectively accomplish the desired results, and can be manufactured. and sold at a comparatively low cost.

Other objects and advantages of the invention will be apparent during the course of the following description.

In the accompanying drawings forming a part of this specification and in which like numerals are employed to designate like parts throughout the same:

Figure l is a side elevational view of a stacker constructed in accordance with my invention, the parts of the device being shown in their normal position.

Figure 2 is a view similar to Fig. 1 showing the position which the parts assume after the cable has been pulled slightly.

Figure 3 is a view also similar to Fig. 1

with the parts in. section, showing a still further position which the parts assume, this view also showing the improved pivoted prop or arm and standard coming into play.

Figure 4 is a view like Fig. 3 showing the final position of the load carrier and other parts.

Figures 5 and 6 are sectional views taken on the planes of the lines 5-5and 6--6 of Figs. 2 and 4 respectively, looking in the direction of the arrows.

Referring to the drawings wherein the preferred embodiment of my invention is clearly illustrated, the numeral 1 designates a base which may be of any suitable form, being here shown as including longitudinal side rails 2 connected by transverse crosspieces 3. Pivoted near the discharge end of the stacker to the side rails 2 is a pair of arms 4; which carry, at their outer ends, a suitable fork on which the hay or other load is placed. As before intimated, this fork is elevated through the medium of a lever or beam 6 which is pivoted intermediate its ends ona swinging standard 7, the latter being pivotally connected to the base adjacent the rear end thereof. The standard 7 couldbe of any suitable construction, but it preferably includes spaced bars which are pivoted to a longitudinal piece 8, which is in turn connected to the centers of the transverse cross-pieces 3 (better shown in Figs. 5 and 6). A flexible element 9 serves to provide a novel connection between the beam 6 and arms 4 of the carrier, and as this beam is provided with a plurality of holes near this end an adjustable connection is provided. With this arrangement, the leverage may be changed to permit the carrier to be more readily elevated. Attention may also be directed to the fact that the beam 6 is provided near its center with a plurality of holes to enable the pivot point to be changed and the leverage in turn changed. In order to impart movement to the beamfi, I make use of a cable 10 which may be connected at various points with any part of the structure. but is preferably connected at its inner end to a cross-pin 11 carried by the combined stop and prop member designated by the numeral 12. (To be hereinafter more thoroughly described.) 4

It has been before intimated that I employ a novel pivoted prop for co-operation with the standard to assist in moving the latter toward the discharge end of the device, and for also functioning in another way to be hereinafter described. This member comprises one or more arms 13 which are pivoted to the aforesaid longitudinal bar 8 near the rear end of the latter and slightly beyond the pivotal connection ofthe standard 7 These arms are shorter than the arms 7 and carry at their free end, a roller or rollers 14;, which are designed to bear against the arms 7. The arms 13 in addition to beingequipped with these rollers 14, carry the aforesaid cross-pin ll and a groovedpulley 15 over which the cable 10 passes. This cable prior to passing over the pulley 15, passes over a similar pulley 16 on the forward end of the rocking beam 6 and after passing over these two pulleys 15 and 16, it passes beneath a third pulley 17 disposed between the arms 7 and finally beneath a loosely mounted pulley 18 'on theforward end of the longitudinal piece 8. Atthis'point, I wish to direct attention tothe fact that thepulley 18 may be mounted in any suitable way, but it is desired that it have free movement to prevent breakage and disconnection in cases where the horse does not'walk in a straight line. Referring again to the-arms 7, it will beseen that they are equipped near their upper 'ends with laterally extending stop pins '19 and these pins bear on the roller 141' when the parts of the device are in normal position. Thus, the member 12, as

' before stated, iscausedto function as a prop for the standard and it limits the movement of said standard in a rearward direction, that is, in a direction toward the load elevating fork. I e

Other parts employed in the make-up of the device include pivoted stay-rods or bracerods 20 for the standard, a counterbalancing weight 21 carried by the beam 6, and a cable or other flexible element 22 for limiting the movement of the load carrier toward the dischargeend of the device. I also make use of an anti-friction roller'23 and place this roller at the forward free. end of the rocking beam 6 and in use, this roller comes into engagement with thecable 10 after the beamassumes a true'vertical position and thus causes the beam 6 to act as a brake and in sodoing, causes theparts 6, 7 and 12 to come into play and move, as a unit, toward the discharge end of the device,= thus more effectively-distributing the pull and reducing it to a minimum and bringing about easy and effective elevationof the load carrier. At this point, it may be well to direct 'attentionto the fact that the weight 21 is of asize topasseasily between the bars 7 of said standard. One of the functions of this weight is to assistin moving the adgacent-endofthebeamfi downwardly. It 165 also; functions to retain; the beam in such stack.

lows: Under normal circumstances, the fork 5 and arms 4t rest in a position close to the ground and a horse-drawn rake deposits the load of hay or the like on the fork. Then the cable 10' is drawn in the direction indi cated by the arrow A by means of a horse or any other suitable power and a rocking movement is imparted to the beam 6 cansing the forward end of the latter to move downwardlythrough an are. It is to be noted that when the cable is first pulled, the

swinging standard 7 and its prop 12 remain stationary until the beam assumes a true vertical position. At this point, the antifriction roller '23 comes into engagement with the adjacent part of the cablelO and its pivotal movement is stopped. It thus functions-as a brake andcauses the standard and prop to come into play, that is to move on their pivots toward the discharge end of the device and carry the load-elevating device to the vertical position shown in Fig. 4 from which position, the load is dumped onto the li hen the parts 7 and 12 come into play, the last named part receives the direct pull of the cable. Attention is directed to the fact, that as soon as the rocking beam stops functioning; the standard 7 comes into play and moves the load-carrier to its final dumping position. Hence, the parts 6 and 7 act in quick succession and no time is lost tion, the weight 21 causes the beam to move to a position where anti-friction roller 23 is disengaged'from the cable. ,By employing this anti-friction roller and by causing it to become quickly disengaged from the cable after the beam 6 stops functioning so far as the movement ofthe load-elevating device is concerned, undue'wear on the cable and possible binding of the latter against the end of the beam is prevented. It is understood, as before indicated,that'the flexible element serves to limit the upward movement of the load-carrier and to prevent it from toppling over on the stack. It is also to be understood, that the; load-carrier through its own weight, is automatically returned to its normal loading position and asv the other parts of the device-assume their normal position,

the lateral stoo- 3ins19 ceme into engagea Q i 44 Y ment with the roller 14 and limit the swinging movement of the standard in this direction. v i

From the foregoingdescription, it will be seen that l have devised a hay stacker which is an improvement over prior devices of this kind, several new features being accomplished with the construction and arrangement which I employ. One of these features, as already set forth, resides in the employment of the two independent and separate levers or members for moving the load -carrier to dumping position. These members are so arranged and co operate with each other in such a way that they operate in quick succession and insure quick movement of the load carrier to the aforesaid position. In addition to the above features, attention is again called to the fact that the leverage may be easily and readily changed in case the load is found too heavy and the pull too hard which would place the animal, used as a power, under unnecessary strain. The number of pulleys and relative positions of the same, enables me to di root the cable over them in such a way that a uniform and easy pull on the cable is insured. Furthermore, by equipping the rocking beam at its forward end with the antifriction roller, undue wear on the cable is prevented and binding of the latter against this end of the beam islikewise prevented. These and other features and advantages of the invention have, no doublt, become apparent from the foregoing description and drawings.

A careful consideration of the description taken in connection with the drawings is thought to be sufficient to enable persons skill d in the art to which the invention relates, to obtain a clear understanding of the same. Therefore, a more lengthy description is thought unnecessary.

Advantageous and effective results may be obtained with the construction and arrangement herein shown and described, and for this reason, this construction and arrangement is taken as a preferred embodiment of the invention. However, I wish it to be understood that various minor changes in the shape, size, and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoined claims.
